Factors like engine compression and the air-fuel ratio can affect the power output of each cylinder in your engine. If you think your vehicle’s engine has problems, you should connect a scan tool to check if codes like the P0284 code have been stored.
The P0284 code is defined as “Cylinder 8 Contribution/Balance.” The PCM is able to measure how much power each cylinder is able to produce by measuring how much the crankshaft accelerates during the power stroke of each cylinder. The powertrain control module (PCM) triggers this code when it detects that cylinder #8 isn’t producing the desired amount of power.
Note: The definition of code P0284 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
The issues that trigger the P0284 code are commonly caused by the following issues:
Your vehicle might exhibit the following symptoms if the P0284 is stored:

Diagnosing this DTC might involve doing visual inspections and perhaps even running tests on some components like the fuel injectors and wiring. These tasks can require technical knowledge and specialized tools. If you think this is daunting, then you should leave it to a professional mechanic.
